###¤£$^«^, trains are so constructed that they ,^«^$£¤###
###¤£$^«^, have to follow a set path. this path is ,^«^$£¤###
####¤$^«^, called a "railway", which is comprised ,^«^$¤####
##££^^,,,, of two metal rails, hence its nickname. ,,,,^^££##
###¤£$^«^, ,^«^$£¤###
###¤£$^«^, because the low friction between the ,^«^$£¤###
¤¤£££$^«^, wheels of the train and the rail metal, ,^«^$£££¤¤
###¤£$^«^, there are limits for how acute a curve ,^«^$£¤###
####¤£$^«, can be, and even more so for how much ,«^$£¤####
#¤£^^^^^,, the ground under the rails can be ,,^^^^^£¤#
###¤£$^«^, sloped. thus a railway is often not led ,^«^$£¤###
###¤£$^«^, on top of hills, rather through them in ,^«^$£¤###
###¤£$^«^, tunnels (if they are large), or ,^«^$£¤###
###¤£$^«^, artificial chasms. ,^«^$£¤###
###¤£$^«^, ,^«^$£¤###
##¤¤£$^«^, there will be trees on the side of the ,^«^$£¤¤##
####¤$^«^, rails, but not too close, or they will ,^«^$¤####
¤£^«^^,,,, be cut down by the railway janitors. ,,,,^^«^£¤
###¤£$^«^, there will be plains, and bodies of ,^«^$£¤###
##¤£^^««^, water. ,^««^^£¤##

####¤£$^«^ trains go by day and by night. along ^«^$£¤####
####£$^«^, the way, there is information ,^«^$£####
###¤£$^«^, scattered, often put on top of poles, ,^«^$£¤###
¤$«,,,,,,, to be interpreted by the train drivers. ,,,,,,,«$¤
###¤£$^«^, different parts of the railway have ,^«^$£¤###
###¤£$^«^, different speed limits. ,^«^$£¤###
#££$^^,,,, ,,,,^^$££#
###¤£$^«^, sometimes, trains have to stop and wait ,^«^$£¤###
###¤£$^«^, for something to happen, far away. this ,^«^$£¤###
####¤£$^^, is signaled by red or green lights. ,^^$£¤####

###¤£$^«^, many people follow the rails by foot. ,^«^$£¤###
####¤£$^«^ often this proves to be the shorter ^«^$£¤####
###¤£$^«^, path between two points. however this ,^«^$£¤###
###¤£$^«^, is frowned upon, and very impolite ,^«^$£¤###
